I've already written about the "hybrot" -- the rat-brained robot -- here. Now, Georgia Tech researchers say that they can control the movements of this robot by a network of cultured neuron cells. EurekAlert! carries a new story about the "hybrot."Steve Potter and his research team in the Laboratory for Neuroengineering at the Georgia Institute of Technology are studying the basics of learning, memory, and information processing using neural networks in vitro. Their goal is to create computing systems that perform more like the human brain.
As the lead researcher on a $1.2 million grant from the National Institutes of Health, Potter is connecting laboratory cultures containing living neurons to computers in order to create a simulated animal, which he describes as a "neurally-controlled animat."
"We call it the 'Hybrot' because it is a hybrid of living and robotic components," he said. "We hope to learn how living neural networks may be applied to the artificial computing systems of tomorrow. We also hope that our findings may help cases in which learning, memory, and information processing go awry in humans."
It sounds like exotic research, but what are the potential usages?
Potter's group hopes the research will lead to advanced computer systems that could some day assist in situations where humans have lost motor control, memory or information processing abilities. The neural interfacing techniques they are developing could be used with prosthetic limbs directly controlled by the brain. Advances in neural control and information processing theory could have application, for example, in cars that drive themselves or new types of computing architectures.

Famous quotes containing the words researchers, cultures, control and/or device:
“When men and women across the country reported how happy they felt, researchers found that jugglers were happier than others. By and large, the more roles, the greater the happiness. Parents were happier than nonparents, and workers were happier than nonworkers. Married people were much happier than unmarried people. Married people were generally at the top of the emotional totem pole.”
—Faye J. Crosby (20th century)
“Both cultures encourage innovation and experimentation, but are likely to reject the innovator if his innovation is not accepted by audiences. High culture experiments that are rejected by audiences in the creator’s lifetime may, however, become classics in another era, whereas popular culture experiments are forgotten if not immediately successful. Even so, in both cultures innovation is rare, although in high culture it is celebrated and in popular culture it is taken for granted.”
—Herbert J. Gans (b. 1927)
“Religion differs from magic in that it is not concerned with control or manipulation of the powers confronted. Rather it means submission to, trust in, and adoration of, what is apprehended as the divine nature of ultimate reality.”
—Joachim Wach (1898–1955)
“Syntax is the study of the principles and processes by which sentences are constructed in particular languages. Syntactic investigation of a given language has as its goal the construction of a grammar that can be viewed as a device of some sort for producing the sentences of the language under analysis.”
—Noam Chomsky (b. 1928)
